This is good news. Still no multisampling though.

To see if your graphics card supports stereo, run the
/usr/X11R6/bin/glxinfo program inside of xterm and there should be an
occasional y in the st/ro column. That will only be true for Macs with
the NVidia Quadro graphics cards. So if you didn't buy a PowerMac or Mac
Pro with the high-end NVidia graphics card, you're out of luck.
FYI, the latest version of chimera can switch into stereo on the fly by
changing the camera mode in the Camera tool.
